 1. App.xaml and App.xaml.cs. These files represent the entry point of the WPF application. App.xaml is used to define application-wide resources, such as styles, control templates, and other XAML resources. App.xaml.cs is the code-behind file for App.xaml and contains the application's startup logic, event handling for application-level events (like Startup, Exit, and DispatcherUnhandledException), and any other application-wide code.
 2. MainWindow.xaml and MainWindow.xaml.cs. These files implement a main window that serves as the primary UI for the application. MainWindow.xaml is used to define the layout and elements of the main window, including control-like buttons, text boxes, and data grids. MainWindow.xaml.cs is the code-behind file that contains the logic to handle events and interactions within the main window.
 
-Now that your project is set up, you are ready to begin development. As mentioned earlier, the application will perform intense computational tasks. You will use the multiply-add vector operations, implemented in the [.NET MAUI learning path](/learning-paths/laptops-and-desktops/win_net_maui).

 ## Helpers
 Start by creating two new helper classes: **PerformanceHelper** and **VectorHelper**. The first class will be used to measure code execution times, while the second class will implement vector operations.
